THIS PROJECT WILL STUDY THE REMOVAL OF SOX FROM COM- BUSTION PROCESS FLUE GASES FOLLOWED BY DIRECT CONVERSION TO ELEMENTAL SULFUR, USING CHELATED IRON THAT HAS BEEN REDUCED TO FORM A CHELATE:FES COMPLEX. THE PROCESS WOULD HAVE SALEABLE ELEMENTAL SULFUR AS THE ONLY SIGNIFICANT BYPRODUCT AND WOULD OPERATE WITH THE CHELATED IRON AS A REGENERABLE CATALYTIC REAGENT. THE REACTIONS TO BE EXAMINED IN THIS ...

A STEAMFLOODING/STEAM GENERATION SYSTEM IS PROPOSED FOR DEEP, HEAVY OIL RESERVOIRS. THIS CONCEPT MINIMIZES THE DOWNHOLE HEAT LOSSES, IMPROVES RELIABILITY AND REDUCES THE COST OF STEAM GENERATION. ITS FEATURES WILL MAKE STEAMING OF VERY DEEP WELLS (BELOW 7500 FEET) TECHNICALLY AND ECONOMICALLY FEASIBLE, AND WILL IMPROVE THE ECONOMICS OF SHALLOWER WELL STEAMFLOODING. THIS NOVEL CONCEPT SUPPLIES HEAT ...

PREVIOUS RESEARCH HAS INDICATED THAT THE THERMOPHILLIC BACTERIA, SULFOLOBUS ACIDOCALDARIUS, AND POSSIBLY RELATED VARIANTS, CAN REMOVE 75% OF THE SULFUR PRESENT IN HIGH-SULFUR COAL IN 3 TO 4 DAYS USING ELEVATED TEMPERATURES AND ACID CONDITIONS. THIS RESEARCH PROGRAM WILL DETERMINE, USING A BENCH-SCALE, FED-BATCH SYSTEM, THE RATE AND EFFICIENCY OF SULFOLOBUS DESULFURIZATION ON AQUEOUS COAL SLURRIES. ...

A NOVEL CHEMICAL FUEL, FIRED COMBUSTOR IS PROPOSED FOR USE AS A LOW COST HEAT SOURCE TO SIMULATE A CLASS OF NUCLEAR REACTORS, INCLUDING THE SOLID CORE, COLLOID CORE, AND GAS CORE NUCLEAR REACTORS, WHICH OPERATE AT PEAK STAGNATION TEMPERATURES BETWEEN 2000-5000OK. SINCE THIS TEMPERATURE RANGE IS COMPATIBLE WITH NON-EQULIBRIUM, MHD GENERATORS, WE ALSO PROPOSE TO DETERMINE THE FEASIBILITY OF USING A ...

LOW TEMPERATURE MOLTEN SALTS BASED ON AL, FE, AND B ARE KNOWN. RECENTLY, UNIQUE ORGANIC CHEMISTRY HAS BEEN DEMONSTRATED IN THESE EUTECTIC MIXTURES. THESE LOW TEMPERATURE EUTECTICS ( 100 DEGREE(C)) ARE ATTRACTIVE MEDIA FOR COAL CONVERSION. THE EUTECTICS SHOULD DISSOLVE LARGE QUANTITIES OF HYDROGEN. BY CONTROLLING THE ACIDITY OF THE MIXTURES, COAL CLEAVAGE REACTIONS SHOULD BE ENHANCED. ETHER CLEAVAG ...

ION EXCHANGE HAS PROVEN USEFUL FOR DECONTAMINATION OF RADIOACTIVE WASTE WATERS. ZEOLITES ARE NOW USED FOR THIS TASK. ZEOLITES SHOW SEVERAL ADVANTAGES OVER OTHER ION EXCHANGE MATERIALS. ION EXCHANGE RATES AND CAPACITY OF ZEOLITES ARE HIGH. ZEOLITES ARE ALSO EASILY HANDLED. HOWEVER, OPTIMUM SIZE OF ZEOLITES FOR ION EXCHANGE IS APPROXIMATELY 10-50 MESH. THE HOT ZEOLITE MUST BE CONVERTED TO A GLASS-LI ...

THE COUNTER CURRENT SOLID STREAMS HEAT TRANSFER (CCSSHT) RETORT IS A NEW PROCESS FOR EFFICIENT OIL RECOVERY FROM OUR PLENTIFUL TAR SANDS AND OIL SHALE RESERVES. AS A HEAT RECOVERY SOIL INCINERATOR, IT HAS THE ADVANTAGES OF REDUCED FUEL DEMAND AND LOW COMBUSTION GAS PRODUCT (REDUCING AIR POLLUTION CONTROL NEEDS FOR THE INCINERATOR). THE CCSSHT UNIT IS A SINGLE VESSEL ROTATING KILN THAT (1) PREHEATS ...

THE PROBLEM TO BE SOLVED BY THE PROPOSED PROGRAM IS THE LIMITED PERFORMANCE OF PHOTOVOLTAIC RECEIVERS IN CURRENT CONCENTRATOR MODULES, DUE TO FIRST-SURFACE REFLECTION LOSSES FROM THE TRANSPARENT CELL ENCAPSULANT, SHADING LOSSES DUE TO GRIDLINES ON THE ILLUMINATED SURFACE OF THE CELL, AND TEMPERATURE-INDUCED LOSSES RESULTING FROM THE CELL-TO-HEAT SINK GRADIENT. THE OBJECTIVE OF THE PROGRAM IS TO EM ...
